ill give another 10 points for the most interesting physics orientated fact?preferably2 do with universe/space

Answer 1

Proposition 1: Gravitation (Newton):
==========================
Gravitation is a force that attracts one mass (M1) towards another (M2) this force decreases if the distance between M1 and M2 increases.

This simple fact is enough to explain why when you throw an apple it will fall to the ground but also why the earth orbits around the sun or the movement of galaxies

Proposition 2:Doppler effect:
=====================
When a wave source (light, sound,...) moves towards you the frequency of the wave increases (higher pitched sound and light going toward red color).

This allows by looking at star colors to know if a star goes toward or away from us and at which speed

Proposition 3 spectroscopy:
====================
When heated any atom or molecule emit a specific set of color bands that can be separated in a prism (i.e. to make a rainbow) By looking at those bands (i.e. what colors are present in the observed rainbow) you can identify what atom/ molecule are present on a star (without having to go there!)

Answer 3

if you were to stand on a hypothetical planet on the other side of the galaxy with a hypothetically powerful enough telescope to look back at earth you would see the dinosaurs! the light hitting the lens of the telescope would have taken so long to travel across the galaxy to your telescope that you would be seeing the Jurassic period! This questions the idea of sending radio transmissions into space seeking extra terrestrial life as even if they did reply we'd all be long gone by the time the message arrived!

Answer 4

If you drop from a great height without a parachute, your terminal velocity will be about 180mph
If you accelerate at 1 gravity continuously, and do that on your way to the Andromeda Galaxy (2.2 Million light years!), then flip over at the halfway mark and decelerate the rest of the way, your subjective travel time would be about 29 years.

Answer 5

You have probably heard that the speed of light appears constant for any observer. Einstein stated that gravity resulted from the 'curvature' of space time and the bending of light in a gravitational field resulted from light 'following the curve'. Some scientist believe the path of light is actually allows straight and that the curvature of space only make it appear to bend.

Answer 6

1. If you could drive your car straight up you would arrive in space in just over an hour
2. When a flea jumps, the rate of acceleration is 20 times that of the space shuttle during launch
3. The speed of light in meters is 299,792,458 meters per second. And how on Earth are you going to remember that? The number can be remembered from the number of letters in each word of the following phrase: "We guarantee certainty, clearly referring to this light mnemonic
4. The speed of sound travels through ice-cold vapour at approximately 4,708 feet per second, ice-cold water at 4,938 feet per second, granite at 12,960 feet per second, hardwood at 12,620 feet per second, brick at 11,960 feet per second, glass at 16,410 to 19,690 feet per second, gold at 5,717 feet per second, and silver at 8,658 feet per second
5. The Sun takes about 220 million years to make one revolution of the Milky Way

Answer 7

The universe has no population.
there are a finite number of planets and some of them are populated but as space is infinate and any finite number divided by infinity is so close to zero that it is hardly worth bothering about.
Therefore anyone you meet is just a figment of your imagination.

Answer 8

There are no facts in physics. Only observations and theories.

Answer 9

there's alot of space outhere so there has to be Aliens

Answer 10

god actually mad us and there are aliens!!
